Full-grouting sleeve for steel bar connection of assembly-type building, and construction method for full-grouting sleeve

Abstract

The invention discloses a full-grouting sleeve for steel bar connection of an assembly-type building. The sleeve is characterized by comprising a rectangular pipe orifice (10), a first reducer pipe body (3), a second reducer pipe body (7), a round pipe orifice (13), a transition pipe body used for communicating between the first reducer pipe body and the second reducer pipe body, a pulp dischargehole (11) and a grouting hole (12), wherein axial cross sections of two ends of the transition pipe body are square; the upper end of the transition pipe body gradually changes to the rectangular pipeorifice through transition and shrinking of the first reducer pipe body; and the lower end gradually changes to the round pipe orifice through transition and shrinking of the second reducer pipe body. The sleeve disclosed by the invention has the beneficial effects that the structure is simple; application cost is low; the length of the full-grouting sleeve and cross sections of corresponding beam columns can be greatly reduced; and tensile strength of the full-grouting sleeve is further enhanced, and application cost of the assembly-type building is further reduced.

Description

technical field [0001] The invention relates to the technical field of prefabricated building steel bar connection, in particular to a full grouting sleeve for prefabricated building steel bar connection and a construction method thereof. Background technique [0002] The prefabricated concrete building refers to the reinforced concrete prefabricated components produced in the factory, and the concrete structure building is designed and constructed through on-site assembly. It has the advantages of shortening the construction period, saving energy and environmental protection, saving materials, saving materials, and reducing manpower. It has become a new direction for the development of my country's construction industry. [0003] Reinforcement grouting sleeve connection refers to inserting a single ribbed steel bar into a metal sleeve and injecting a grouting material mixture. The mixture is hardened to form a whole and realize the butt connection of the steel bar for force ...
